mount.nfs4: access denied
by Bob Goodwin
.
I replaced my router with a different one and changed the ipaddress and
now I can not mount the NFS server, the "fstab" lines show it best:
First router:
# 192.168.50.32:/nfs4exports/home /media/nfs nfs4
re,soft,int,ff,comment=systems.autonomous 0 0
Second router:
192.168.2.128:/nfs4exports/home /media/nfs nfs4
re,soft,int,ff,comment=systems.autonomous 0 0
When I try to mount the second router "access' is denied,
[root@localhost /]# mount -a
mount.nfs4: access denied by server while mounting
192.168.2.128:/nfs4exports/home
I did not make any change to the NFS server, It was working before the
change and the second router has always worked and still does, I can ssh
to it, the apple iPhones/iPads, whatever, (they do not use NFS) can
connect to the wifi, but I can not mount NFS with my wired connection
from the desktop.
/I did not expect this problem, some help appreciated, *Bob

Web camera works intermittently as for recently
by Paul Smith
Dear All,
I have a web camera, which has worked perfectly on Fedora 32. However,
recently, it only works intermittently on Skype. Intriguily, if I plug
it into a different USB port, the web camera works with no problem.
Any ideas?
Thanks in advance,
Paul

fedora packages
by ITwrx
I'm trying to find out why the nim-lang package "nim" is very old (q4
2019), but when i go to https://apps.fedoraproject.org/packages/ i get a
503.
Am i going to the right place to see the source code, build status of
the package, and who the maintainer is, etc?
thanks

F33 Grub Administration Changes?
by Ed Greshko
On previous versions and versions updated to F33 I would see the following.
[egreshko@meimei ~]$ sudo grub2-editenv list
saved_entry=a48313ea54924eef8eca07a507b7541f-5.8.13-200.fc32.x86_64
boot_success=1
boot_indeterminate=0
kernelopts=root=UUID=4455f2e9-fed2-4e1e-856d-642b531547f9 ro rd.driver.blacklist=nouveau modprobe.blacklist=nouveau nvidia-drm.modeset=1 nomodeset
So, I could use grub2-editenv to modify the kernelopts line.
However, now with a fresh install of an F33 system I see
[egreshko@f33k ~]$ sudo grub2-editenv list
saved_entry=8b511c4b483b4414b7bf742b35809e2c-5.8.14-300.fc33.x86_64
boot_success=0
boot_indeterminate=0
Is there a new way to modify the kernel options?
The "saved_entry" format is slightly different as well with the "options" line.
For F32
options $kernelopts
For F33
options root=UUID=e1664725-d90c-4a19-b1d6-86eca7cba8a7 ro rootflags=subvol=root rhgb quiet
Seems to me the previous way has advantages?

OT: script to check Lotto numbers
by olivares33561＠protonmail.com
Dear fellow Fedoreans,
I have some friends that play Lotto Texas and they buy tickets playing the same numbers every Wednesday and Saturday. I subscribed to get the winning numbers. If you match 3 or more numbers you are a winner.
The email has the following information
<Quote>
Texas Lottery - Lotto Texas - Winning Numbers for 10/10/2020
2 - 7 - 23 - 38 - 51 - 53
Lotto Texas Advertised Jackpot for 10/14/2020
Annuitized: $5.75 Million; Cash Value: $4.76 Million
</Quote>
The play 15 different sets of numbers and to check if they won any prize a script using a chain of if statements or case statements would be correct to implement this. AWK may also do the job?
There are six numbers that we need to check let us suppose that we had the numbers in a file numbers.dat and it has the fifteen combinations
2 - 3 - 5 - 7 - 11 - 13
...
...
15 versions
Check against the winning numbers
2 - 7 - 23 - 38 - 51 - 53
Faster way to check compare string? Compare numbers one by one and check for at least 3
If (successful numbers >= 3)
Write you have won $3
If (successful numbers >= 4)
Write you have won $56
If (successful numbers >= 5)
Write you have won $156
If (successful numbers > 5)
Write you are a millionaire and have won the jackpot
The script will check for 3 or more numbers and write if we have winning numbers or not. A bash script can do the job, or use AWK, grep or other commands. I do not know if one uses (if commands or case commands)
Any pointers, tips are greatly appreciated.
Best Regards,
Antonio

tar and cores?
by ToddAndMargo
Hi All,
I am noticing that
tar czvf xxxxx
is only using one of my cores (and pretty much all of
the core).
Is there a way to get it to use more than one core?
Many thanks,

Re: Slow down problem
by ToddAndMargo
Hi All,
It looks like my original eMail with embedded picture
is going to get bounced, so this one substitutes links
to the images. Sorry for the extra work of having to
click on the links.
My slow down problem is back. And I FINALLY have
some good data to show:
Here is bpytop. Note that core 2 is swamped at 98%.
https://ibb.co/MkNH6vC
And here is htop with the same result. Core 2 is at 96%:
https://ibb.co/dpYySq6
And as you can tell from bpytop, htop, and the following, no
process is showing hardly anything:
# ps -eo pid,ppid,cmd,%mem,%cpu --sort=-%mem | head
PID PPID CMD %MEM %CPU
18455 1 /usr/bin/qemu-system-x86_64 26.2 10.7
18760 16233 /usr/lib64/thunderbird/thun 2.6 2.1
19484 18865 /opt/vivaldi/vivaldi-bin -- 2.0 1.0
18854 16233 /opt/vivaldi/vivaldi-bin -- 1.5 1.4
20101 18865 /opt/vivaldi/vivaldi-bin -- 1.3 0.4
18927 18865 /opt/vivaldi/vivaldi-bin -- 1.1 1.3
19520 18865 /opt/vivaldi/vivaldi-bin -- 1.1 0.5
21841 1 gimp-2.10 /tmp/Screenshot_2 1.0 0.3
14960 1 /usr/libexec/mysqld --based 1.0 0.0
And here are my core temperatures. Core 2 is not abnormal:
https://ibb.co/2dccsSS
And I can't get Google to cough up how to tell me
what is running on a particular core.
Both "lynis" and "chkrootkit" (root kit scanners) show me clean.
And a reboot ALWAYS clears the issue. When not an issue, I
have run fro two solid days without a problem. This time it
happened within a half hour.
Any words of wisdom? I will hold off rebooting until
I have to do my backups tonight.
Many thanks,
-T
I am starting to think my CPU is going bad, but it would
stay bad after a reboot. so ...

Printer on UPS?
You gotta be joking. Computers and switches OK.
But printers will empty your batteries in moments.

Subject: Re: Slow down problem
And on top of what George says, it might be best to make sure the
printer is on the same breaker/120Leg as the computer.
If the computer is on a UPS and the printer is not then if possible
make sure the printer is plugged into the same outlet as the UPS.
Also note that I don't know which power system you are on, I am
familiar with the US hot/neutral/ground 3-prong plug which is supposed
to just work for this, but there are a number of mis-wirings (of both
the outlet and the device) that are common enough to not be unlikely.
In the US there are simple <$10 devices (most hardware stores) that
plug into outlets and light up and tell you if the outlets are wired
correctly.
Weird ground issues produce really odd behavior. If everything
involved is using a proper ground outlet and the outlets are properly
ground and all of the devices are properly wired then you should not
have a weird ground issue, which is what this sounds like, and was why
Geroge mentions running a wire to make sure the ground is right. If
you have a multimeter you could check resistance between a metal part
on the printer and a metal part on the computer without the printer
cable attached, if everything is right the resistance should be almost
0, if the resistance is not almost zero then something really is wired
wrong. If the resistance is non-zero then there is a decent chance
that the ground on one device vs the other could be a few volts
difference (you can also check that with the meter, but it may or may
not be different enough at the moment), with a small amount it will
think there is a signal when there is not, and with a larger
difference any electronics (the parallel port card) may burn because
there is current flowing were it is not designed to flow.

What happened to 'env'?
by Patrick O'Callaghan
For as long as I can remember, the shell builtin 'env' has been useful
for listing all the current environment variables.
Not any more. There's another command called env which does something
different, and the builtin no longer exists.
I mustn't have got the memo. How do I get the old 'env' back?
